High-rise ventilation systems are critical for maintaining air quality, comfort, and safety in multi-story buildings. Due to their complex design – with risers running the full height of the building and smaller spigots feeding individual rooms – these systems are particularly susceptible to dust, debris, and particulate build-up. Over time, this can reduce airflow, increase the load on air handling units, and compromise indoor air quality, posing health risks to occupants and affecting overall system efficiency.
Regular cleaning and inspection of high-rise ventilation ductwork are essential to comply with UK health and safety legislation. Thorough maintenance removes accumulated particulates, microbes, and odours, ensuring the system operates efficiently and safely. With a professionally managed cleaning programme, building owners and managers can maintain compliance, improve indoor air quality, and protect occupants from airborne contaminants.
Contact Marlowe Environmental Services today to schedule high-rise ventilation ductwork cleaning and ensure your systems are safe, hygienic, and fully compliant.
Industrial HVAC systems are prone to the accumulation of dirt, dust, and debris. Over time, this buildup can impact:
Ductwork can host:
Unclean systems not only reduce operational efficiency but can also pose health risks to building occupants.
High-rise ventilation differs from general ventilation systems in several ways:
Regular monitoring and cleaning are critical to maintaining both system efficiency and compliance with safety regulations.
Sleeping accommodation areas in high-rise buildings are particularly sensitive due to:
Longer occupancy periods
Lower air change rates (sometimes due to occupant adjustments or building modifications)
Additional vulnerability to indoor air quality issues
Scheduled cleaning and monitoring allow the responsible person to maintain compliance and ensure occupant safety.
Sick Building Syndrome occurs when occupants experience health issues linked to the indoor environment, often due to poor ventilation.
Common symptoms include:
Headaches
Blocked or runny nose
Dry or itchy skin
Dry, sore eyes or throat
Coughing or wheezing
Rashes
Fatigue or difficulty concentrating
Proper ventilation ductwork cleaning helps mitigate these risks and improves occupant wellbeing.
Our work is aligned with UK legislation and industry guidance:
BESA TR19 – Internal Cleanliness of Ventilation Systems

Ductwork should be cleaned regularly based on occupancy type, system usage, and compliance requirements, typically every 12–24 months for high-rise buildings.
Yes. Removing dust, debris, and microbial growth improves airflow, reduces strain on fans, and enhances heat exchange efficiency.
All ductwork cleaning is certified in accordance with BESA TR19 guidelines to ensure compliance and audit readiness.
Yes. Due to longer occupancy and increased vulnerability, these systems are subject to stricter monitoring, cleaning, and compliance standards.
Yes. We can rebalance airflow and replace grilles after cleaning to ensure the system operates at optimal efficiency.
